Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187480, here are decompositions:

3 + 187477 = 187480
11 + 187469 = 187480
17 + 187463 = 187480
47 + 187433 = 187480
71 + 187409 = 187480
101 + 187379 = 187480
107 + 187373 = 187480
113 + 187367 = 187480

Showing the first eight; more decompositions exist.
